bindings: PCI: artpec: correct pci binding example

- Increase config size. When using a PCIe switch,
   the previous config size only had room for one device.
 - Add bus range. Inherited optional property.
 - Map downstream I/O to PCI address 0. We can map it to any
   address, but let's be consistent with other drivers.
